Been a non member surfer for quite some time now. I have a 73 duster I picked up last winter and plan on a pro-touring road race car out of it. While I have read good things about the torsion bar suspensions on these cars, I am adding a 600 horse 440, 11.5:1 compression, tunnel rammed motor. I was considering their front K frame kits after reading another thread on here and went to their website, it seems they are selling a Watts link 4 bar rear suspension too, does anyone have one? Thoughts on a watts link system?

here's the link to their kit,
